<h3 id="rationale">Rationale:</h3>
<p>A character that looks similar to <code>-</code> has made its way
into your code. This is usually due to copy-pasting from blogs and other
websites that formatted code as text, replacing the ASCII hyphen-minus
with a Unicode dash character.</p>
<p>To fix it, simply delete and retype it.</p>
<p>For a large script, you can use your editor's Search&amp;Replace by
copy-pasting the bad dash.</p>
<h3 id="exceptions">Exceptions:</h3>
<p>None. If you want a literal Unicode dash character, just quote
it.</p>
